SSL Error #38 on Citrix

This afternoon everyone started getting this error:

Cannot connect to the Citrix Xenpp Server.
SSL Error 38: the proxy server denied access to  ..... port 1494

Any ideas?

I have rebooted everything Citrix-related.

Reboot the NetScaler.

- Or -

Remove and then re-add the SSL VIP.

is what the site says.  Is rebooting the NetScaler the same as rebooting the CAG? If so, I already did that.

are you able to telnet from the CAG to your XenApp Server using Port 1494?
You should see ICAICAICA....

do you mean telnet from the Citrix Access Gateway Admin Desktop? I totally don't know how to do that.

Dirk KotteSECommented:
no, the telnet session must be initiated from the CAG Linux-Apliance.
The enduser makes a connection to the appliance with port 443 and the appliance makes connections to the xml-service (to recive the informations to display the user-icons) and then a new connection to the ica-Port (1494) if the user click an icon.
